Five days passed.
Five days flew by like the wind.
And in the span of those five days, intense training was the norm for Toshirou. Everyday was utter hell for the azure-eyed teen, always being pushed to the brink of death and coming out with unsightly injuries and wounds.
The first day, both his arms had been cut off. Blood spilled out of the twitching flesh, and the boy cried out in severe pain and fainted from blood loss.
Yet somehow, when he came to, he was healed.
On the second day, his spine was ripped out of his back, like a cloth being removed from the clothsline. His back was cleaved cleanly into two by Mahalalel's sword, and his spine popped off, rendering the the immobile and ultimately, unconscious.
But yet again, when he woke up, he was completely healed.
